prevent click with mouse hook

Question

Hallo,
I am new i C# and Visual Studio, so perhaps I am asking wrong question.
I want to prevent mouse double click on WinForm's objects but I dont know how :) I have tried mouse hook according to this example http://support.microsoft.com/default.aspx?scid=kb;en-us;318804  but I dont know how to interrupt (end) hook chain.
Can someone help me please?
